Abstract: 821,577. Batteries. CHLORIDE BATTERIES Ltd. March 11, 1958 [March 28, 1957; Sept. 30, 1957; Dec. 4, 1957], Nos. 10146/57, 30494/57 and 37803/57. Class 53. An accumulator plate comprises lead rods and active material enclosed in tubes consisting of woven, knitted or braided yarn made from a polyester resin of terephthalic acid and ethylene glycol. The yarn may be bulked yarn having a false twist. The tubes may be impregnated with a resin which is cured while the tubes are supported on a mandrel. The resin may be urea formaldehyde which is leached out when the plate is immersed in the accumulator acid. Each tube may be made individually, or a row of tubes may be produced in a single weaving operation, the tubes being interconnected by a small width of fabric. The two outer tubes forming the edges of the plate may be of a closer weave than the remaining tubes in order to reduce the porosity at the edges and so reduce the risk of short-circuits.

Title: Sash window assemblies
Inventor: FOX-WILLIAMS JACK
IPC: E06B3/44
Filed: 1959-03-31
Abstract: 907,019. Sash windows. WILLIAMS & WILLIAMS Ltd. March 29, 1960 [March 31, 1959], No. 10903/59. Class 20 (3). A window sash 2 is partly counterbalanced by a spring arrangement 8 and is provided with a frictional braking device 21 which normally prevents vertical movement of the sash but acts to free itself when sufficient force is applied to the sash to move it upwardly or downwardly. As shown, a metallic sash frame 2 is secured by screws 17 to a plate 13 slidable in the main metal frame 1, 3 within which are housings 4, 5 to accommodate torsion-type spring-balancing devices 8, and housings 6, 7 to accommodate the braking devices 21. The tubular housing 9 of the spring balancing device 8 is secured to housing 3 while a twisted rod member is indirectly secured to the plate 13, so that as the sash is raised the twisted rod winds up the torsion spring to keep the balancing action constant. The brake device, Fig. 3, comprises a pair of spring-urged jamming members 21 which engage a flexible strip 31, secured at both ends in the channel 20 and thus to the sash through the plate 13. The movement of the strip 13 towards one member 21 with a force applied to the sash, sufficient to overcome the force of spring 30, allows the strip to move clear of the face 24 of the other member 21 and thus allows the strip to move freely between the faces 24 of the members 21 with only the frictional resistance of the strip against the face 24 against which it bears. Flexible sealing strips 18, Fig. 2, in the end walls 15, 16, prevent passage of moisture into the side member 1. Specification 835,915 is referred to.

Title: Improvements in or relating to the production of a biguanide
IPC: C07C279/26
Filed: 1947-04-24
Abstract: N1-p-Chlorophenyl-N5-isopropylbiguanide is manufactured by the action of ammonia, in the presence of a mercuric halide or mercuric oxide, on the compound, believed to be N1-isopropyl-S1 - methyliso - N3 - p - chlorophenyldithiobiuret, obtainable by condensing isopropyl-S-methylisothiourea with p-chlorophenyl isothiocyanate. The process is preferably effected by keeping a solution of the starting material in liquid ammonia in a closed vessel in the presence of mercuric chloride until amination is substantially complete. Alternatively the reaction may take place in alcoholic or other suitable medium (e.g. toluene), either at or around room temperature under a pressure of ammonia gas of not less than 1-3 atmospheres, or at elevated temperature in a closed vessel, e.g. by using a saturated alcoholic or 40 per cent aqueous alcoholic solution of ammonia, with agitation, until amination is substantially complete.  Examples describe various methods of carrying out the process, including the preparation of the starting material.

Title: Improvements in apparatus for turning stockings and the like
Inventor: LANDUCCI FRANK ANDREW
IPC: A41H33/00
Filed: 1949-04-26
Abstract: 666,280. Turning articles inside out. CHARNWOOD ENGINEERING CO., Ltd. June 22, 1950 [April 26, 1949], No. 11038/49. Class 112. Apparatus for turning inside out stockings and other tubular articles comprises at least one female article-receiving member transported between a loading station and a turning station at which a male turning member enters the receiving member to force the article through it. Preferably several receiving members are moved in rotation past the two stations, pausing at each. A gripper may be provided to draw the article away from the receiving member after turning. In the embodiment shown, four tubular receiving members 1 are fixed to links 6 connecting spiders 2, 3 which are mounted on parallel shafts spaced apart by the length of the links and are rotated step-by-step through Geneva gear by an electric motor 15 controlled by a pedal 17. An article is put over each member 1 when it is in its lower right-hand position, and when it reaches its upper left-hand position a plunger 8 is operated by lazy-tongs 24, actuated by a connecting rod 32 from the Geneva driver, to force the article down inside the tube 1. To obviate the need for a long stroke of the plunger 8, a gripper 36 is actuated to engage the end of the article and withdraw it on to a tray 37 which is then swung down to discharge the article. The gripper 36 is carried by an arm 34 pivoted at 35 and actuated by a cam on the Geneva driving shaft through a lever 39 and link 38, the gripper 'being guided by a link 47 connected to a pivot 48 sliding in a track 41 and connected to the arm 34 by a link 50; a slot 43 in the arm 34 provides for adjustable attachment of the link 38 to vary the stroke of the gripper. The gripper has a pivoted, gravity-opened jaw normally held closed by a spring-pressed rod but allowed to open when the gripper approaches its forward and rearward positions by engagement of the rod with stops 58 on the spider 3 and by a lever actuated through a flexible cable 63 by the lever 39, respectively. The tray 37 is lowered by camactuated mechanism against the action of a spring. The number of articles turned may be registered by a counter actuated preferably through a feeler on the plunger 8 or a member actuated by the article being pulled away from the bottom of each tube 1. The gripping mechanism may be dispensed with, the articles being drawn away by hand instead. The members 1 may be moved in any suitable path, and may be carried by a wheel or an endless chain. The tubes 1 may be replaced by rings suitably supported.

Title: Improvements in or relating to mechanical toys
IPC: A63H18/00
Filed: 1947-04-25
Abstract: 624,533. Mechanical toys. WATSON, A. April 25, 1947, No. 11089. [Class 132 (iii)] A vehicle runs on an inclined track which has means, attached to it, urging the vehicle to the upper end of the track above which there is a hopper. This hopper is operated by means, controlled by the vehicle, so that a weight is discharged on to the vehicle, as it approaches the upper end of the track, causing it to run down the track. As the vehicle approaches the foot of the track, means are operated by which the weight is discharged from it, and the vehicle runs up the track again. This cycle continues until the weights are used up. Preferably, the means pulling the vehicle up the track are a weight attached to a pulley block round which a cord passes, one end of the cord being attached to the track and the other passing over a pulley at the top of the track and being attached to the vehicle. The hopper may consist of a channel, inclined slightly downwards towards the upper end of the track, which has its lower end closed by a weighted flap. This flap projects into the path of the vehicle, near the upper end of the track, and is opened by it and thus releases a weight. This weight is sufficient to pull the vehicle down the track against the force, due to the other weight, which is pulling it up. As shown, a base member 1 has recesses 2 to receive pins 3 which are provided at one end of a track 4. This track is supported at an angle of approximately 45 degrees to the base by a vertical element 5, which is removably secured to the other end of the base member. The track is preferably made up of several pieces, which can be separated, so that it is packed more readily. Attached to a vehicle is a cord 18 which passes over a pulley 19, round a pulley block 20, to which is attached a weight 22, and is removably secured to the track at 21. A hopper 7 is secured to the upper end of the track which consists of side plates 8 between which there is a channel 9 inclined slightly downwards. The weights are held in the hopper by the projection 13 of the strip 10a which is pivoted at 11 to the sides 8. When the strip is rotated, by the vehicle as it approaches the top of the track, one weight is released ; the rest are held by the projection 12 (see the position of 10a shown in dotted lines in Fig. 2). The element 10a may be so weighted that it normally remains in the position shown in full lines in Fig. 2, or may be provided with a spring to retain it in this position. The body of the vehicle may be hinged to the chassis at 24 and provided with a loop 24a which, as the vehicle approaches the foot of the track, engages a rod 6 so that the body is lifted off the chassis and the weight rolls off. Otherwise the vehicle may have a flap, which is opened by a projection near the foot of the track, to release the weight. The track may be of metal with upturned edges or may have rails laid on it. Sand, shot or other granular material may be used instead of weights.
